ユーザーが複数の電子メール通知を受け取る

Question

レコードが更新された後、テーブルを更新して電子メール通知を送信するコードがあります。 休暇を申請するために登録されたメンバーがログインする休暇承認システムです。このコードは、休暇申請を承認または拒否しようとすると、2人のユーザー（従業員）と（従業員マネージャー）に電子メールを送信します。

3人が休暇を申請して1人のユーザーを承認しようとすると、ユーザーは電子メール通知を3回受け取ります。

Answer 1

何かを行うことでフォームの送信をユニークにすることはできますか？

<input type="submit" name="sub_<?php echo $data['id']; ?>" id="button" value="Submit" /> 

$my_index = "sub_".$data['id']; 
if (isset($_POST[$my_index])) { 
............. 
............. 
} 

を以下のようにして自分のフォームで結果を参照してください、任意の変更された場合やありません。 フォームの送信を一意にします。私はそれがここの問題だと思う。
